Abstract: We show theoretically that a simple one dimensional system such as metallicwire can display quantum spin pumping possibly without pushing any charge. Itis achieved by applying two slowly varying orthogonal gate electric fields ondifferent sections of the wire, thereby generating local spin-orbit Rashbaterms such that unitary transformations at different places do not commute.This construction is a unique manifestation of a spin-orbit observable effectin purely one dimensional systems with potentials respecting time-reversalsymmetry.
